-直接在对话中描述你想要的技能，Agent 会自动完成创建：
+Simply describe the skill you want in a conversation, and the Agent will handle the creation:
 
-- 将工作流程固化为技能："帮我把这个部署流程创建为一个技能"
-- 对接第三方 API："根据这个接口文档创建一个技能"
-- 安装远程技能："帮我安装 xxx 技能"
+- Codify workflows as skills: "Create a skill from this deployment process"
+- Integrate third-party APIs: "Create a skill based on this API documentation"
+- Install remote skills: "Install xxx skill for me"
